Always report full_backing_filename, even if it's the same as
backing_filename. In the next patch, full_backing_filename may be
omitted if it cannot be generated instead of allowing e.g. drive_query
to abort if it runs into this scenario.
The presence or absence of the "full" field becomes useful information.

This will let us print options in a format that the user would actually
write it on the command line (foo=bar,baz=asd,etc=def), without
prepending a spurious comma at the beginning of the list, or quoting
values unnecessarily. This patch provides the following changes:
* write and id=, if the option has an id
* do not print separator before the first element
* do not quote string arguments
* properly escape commas (,) for QEMU
